A mobile application platform system for power grid scheduling based on a mobile intelligent terminal comprises a server-side, wherein the server-side comprises a channel processing module and a platform processing module, the channel processing module is used for receiving an access request, allocating a communication channel to an accessor sending the access request, and sending processed business data provided by a platform management module to the accessor via the allocated communication channel according to the type of the business request; and the platform processing module is used for providing the accessor with a power grid mobile scheduling service via the communication channel allocated by a channel management module. The power grid mobile scheduling service comprises receiving the business request sent by the accessor, accessing a corresponding message/multimedia message database or a wireless application platform database according to the type of the business request so as to obtain the corresponding business data, processing the business data according to preset business logic and then providing the processed business data for the channel management module. The system provided by the invention has the advantages that mobile officing is realized on the power grid scheduling based on the mobile intelligent terminal, and the power grid scheduling efficiency is increased.
